The hair roller includes a spiral groove formed on a side edge thereof, extending between first and second ends thereof and adapted for receiving the hair. Thus, the hair wrapped around and received in the groove is unable to slide with respect to the side edge of the hair roller, so that the hair curling device not only can save time but also can control the curvature of the hair easily.

The present application is a continuation-in-part application of U.S. patent application Ser. No. 13/445,973, filed on Apr. 13, 2012, of which the entire disclosure is incorporated herein.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a hair curling device used to form and shape hair and, more particularly, to a hair curling device including a hair roller having a groove to receive the hair securely.

2. Description of the Related Art

Generally a variety of hair rollers which may be heated by steam, by electricity, and by a combination of steam and electricity have been used for imparting curls to straight strands of hair. More particularly, both professional hair stylists and individuals have used hair rollers to alter the shape and configuration of straight hair to approximate the appearance of natural curls.

Most prior art hair rollers have an elongated cylindrical configuration and may be solid or hollow. In use, the hair is separated into groups of strands, with each group of strands being tightly wrapped around the exterior cylindrical surface of the roller. The wrapped strand is then fixed relative to the roller by any suitable means such as a bobby pin. When the strand is unwrapped from the roller after a suitable period of time, curls will be formed along the length thereof.

However, the conventional hair rollers cannot attach with the group of strands of hair securely because they usually have a flat and smooth outside surface so that the hair will slide with respect to the outside surface of the conventional hair roller easily to cause the curvature of the hair to be controlled hardly.

The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.

SUMMARY OF THE INVENTION

According to the present invention, a hair curling device includes a hair roller adapted to provide the hair wrapped and attached on it, and a sheath adapted for surrounding the hair roller. The hair roller includes a spiral groove formed on a side edge thereof and extending between first and second ends thereof being adapted for receiving the hair.

In view of the foregoing, it is an object of the present invention that the hair wrapped around and received in the groove cannot slide with respect to the side edge of the hair roller so that it not only can save time but also control the curvature of the hair easily.

It is another object of the present invention that the hair curling device is adapted to be used to form and shape hair in any length.

It is another object of the present invention that the hair curling device only includes two elements to manufacture easily and faster.

It is further object of the present invention that the second annular portion is firmly coupled with the periphery of the second end face to avoid the sheath and hair roller getting lost easily when detached.

Other objects, advantages, and new features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanied drawings.
